Devilish Duos, as one might expect, provides a pair of villains who work together. In this case the supernatural pair of Smoke, the ghost of a murdered woman, and Mirrors, a woman who long ago made a dark pact with evil entities from beyond our world. Similar to the Threat Report products from Green Ronin the meat of the product are the two villainous characters.

Smoke is a ghost, wronged in life, and murdered, she was unable to move beyond after death and instead has become a restless spirit who kills to ease the pain of her soul. Her powers revolve around her ghostly condition and manipulation of the powers of fire and smoke that ended her life. Her partner, both in mayhem and in love, is Mirrors. Mirrors made a pact with dark gods that granted her powers of invisibility and stealth. In return she kills to make sacrifices to those same dark gods.

Both characters are given full background and personality write-ups, as well as complete stat blocks for Mutants and Masterminds Third Edition. In addition there are character standees, a page worth of adventure hooks, a sidebar about using the pair with the Oktobermen, and some nice full color artwork.

Closing Thoughts:
For $2 you get a pair of supernatural characters, suitable for any darker superheroes game, or modern or gothic horror. The product dovetails nicely with the Oktobermen, being the same genre and approximate power level, and would make a nice add-on for that team in a game (or even possibly villainous rivals).

I love well worked up characters for supers games. I love supernatural characters. And I love products that have appeal across games. While this is an Icons product, I see there are M&M versions out as well. That beign said the value here is in the character write-ups and those can be used anywhere.
Smoke and Mirrors are two such characters. Though I have to think it was just a quirk of chance that made them as they are and but a change in the same fates could have made them...well not good, but certainly not villains, though Smoke could have been had she been allowed to live her life. And that is the key here. Not that these are well stated out or the art is good (true on both counts) or even that there nice little paper minis to use (there is and they are a nice touch) but that they are characters I would want to get to know to use.
Actually I want to use them in a horror game. There they would shine.
The Mutants and Masterminds version includes Hero Builder files, which is also a nice touch.
